Abstract

The invention discloses a device for producing low-carbon olefin by using an oxygen-containing compound in the technical field of petrochemical engineering, which is suitable for the characteristics of quick reaction, strong heat release, lower agent-alcohol ratio, high product selectivity and the like in the process of preparing the low-carbon olefin by using the oxygen-containing compound, so asto solve the problem of low selectivity of the low-carbon olefin in the prior art. Therefore, the advantages of the reaction can be exerted to the greatest extent, and the selectivity of the low-carbon olefin is improved.

Description

technical field [0001] The invention belongs to the technical field of olefin preparation, and in particular relates to an efficient method and device for producing low-carbon olefins from oxygen-containing compounds. Background technique [0002] Light olefins (ethylene, propylene, butadiene) and light aromatics (benzene, toluene, xylene) are the basic raw materials for petrochemicals. The traditional production route of ethylene and propylene is through the cracking of naphtha, which has the disadvantage of being overly dependent on petroleum. Methanol-to-Olefin (MTO for short) is another process route for producing olefins such as ethylene and propylene from methanol. At present, the development of process technology has become mature. The industrialization of MTO technology has opened up a new process route for the production of petrochemical basic raw materials by gasification of coal or natural gas, which is conducive to changing the traditional coal chemical product ...
